Potatoes Au Gratin Ingredients

ingredients of potatoes au gratin
  • Russet Potatoes– You need starchy potatoes like Russet Potatoes. In places like England King Edward potatoes is what works best. Australia, you would use Sebago potatoes.
  • Melted butter-Use full fat, unsalted butter only.
  • Heavy cream– Use full fat heavy cream. If you are looking for something lighter, you can go for half and half, but it wont come out as thick and creamy.
  • Cheese- I used gouda and gruyere, for they are my favorite choices for this recipe. If you feel like it’s a bit pricey, use cheeses like Monterey Jack or White Cheddar Cheese.
  • Herbs- thyme, chives or rosemary. Use dry or fresh herbs and cheese whichever you like best.
  • Ground Black Pepper– use fresh ground black pepper because it provides so much more flavor to the dish.

How To Make Potatoes Au Gratin

  • Prep the potatoes – Peel and wash the potatoes, then slice very thinly and rinse in cold water.
  • Make the gratin sauce – In a Pyrex bowl, add in cream, garlic, herbs, butter and black pepper. Then microwave for a minute to infuse the flavors.
  • Layer – Rub a large baking dish with butter, pour the cream sauce in the bottom then layer in potatoes, cheese and sauce. Repeat until you have three or four layers.
  • Bake – Cover with foil and bake for 1 hour 10 mins then remove the foil and bake for another 20 mins.
  • Allow to rest, garnish, serve and enjoy!

Tips to Make the Best Potatoes Au Gratin

  • Use a preheated oven.
  • Make sure you slice your potatoes nice and thin, otherwise the dish will take longer to cook.
  • Rinse your potatoes and place them in cold water, while you prep the other ingredients, this will stop the potatoes from browning.
  • Ideally shred your on cheese. Pre shredded cheese has anti-caking agents in it, so it doesn’t melt that well.
  • I used an 8×10 inch oval dish. If you use something smaller it can take a bit longer to cook, if you use something bigger, it can be a bit quicker.
  • The cheese should be golden brown before removing from the oven. You can always broil the top a little to achieve the desired color.
  • Use a mandolin to make potato slices easily.
  • Make sure to sprinkle some cheese on top for a crispy cheesy crust
  • Garnish with fresh herbs for a pop of freshness and color.
  • To speed up cooking time, you can always par-boil the potatoes until slightly tender before assembling in the baking dish.

Easy Au Gratin Potatoes

Creamy, Easy Au Gratin Potatoes is a classic side dish that's so easy to make! Potato slices are baked to perfection with a dreamy creamy cheese sauce and a crispy cheesy layer on top.
Prep Time: 20 minutes
Cook Time: 1 hour 30 minutes
Total Time: 1 hour 50 minutes
Servings: 6 servings

Ingredients 

  • 2 lbs. Russet potatoes, peeled, thinly sliced
  • ¼ cup butter, melted, (save 1 tbsp. for the rubbing dish)
  • 2 cups heavy cream
  • cup gouda cheese, shredded
  • cup gruyere cheese, shredded
  • 4 large garlic cloves, minced
  • 2 tsps. fresh thyme, chopped
  • 1 tsp. fresh rosemary, chopped
  • ¾ tsp. fresh ground black pepper

Instructions 

  • Preheat oven to 350 degrees F.
  • Peel and wash the potatoes. Slice potatoes very thinly, about 1/8 of an inch or 2-3 mm thick. Rinse the potatoes and keep in cold water to prevent them from browning.
  • Shred the cheeses, chop the herbs and melt the butter.
  • In a Pyrex measuring cup or bowl, add in the heavy cream, minced garlic, herbs, melted butter, and black pepper. Cover with saran wrap and microwave for 1 minute. This will infuse the flavors of the garlic and herbs together.
  • Rub a large baking dish with butter, mine was an 8 x 10 inch oval dish. If you use something smaller it may take longer to cook. If you used something larger, it may take less time to cook. You can use your judgement.
  • It's time to layer up the potatoes. Save 1/4 cup of cheese from each kind for topping later.
  • Mix the heavy cream mixture well and pour in 1/4 cup of the sauce to the bottom. Add a layer of potatoes, then some shredded cheese (from both), and another 1/4 cup of the heavy cream mixture and keep repeating until you get 3-4 layers of potatoes. Pour in any extra cream on the top layer.
  • Cover with foil wrap and bake in the over for 1 hour and 10 minutes. Remove the foil wrap and then top with the extra cheese you saved and bake uncovered for another 20 minutes or so. The cheese should be golden brown before removing from the oven.
  • Remove from the oven and let it rest for 5 minutes. Garnish with some fresh herbs and serve.
